Conductive member for touch panel and touch panel

A conductive member for a touch panel, comprising:

• a substrate;
• and
• a plurality of first electrodes which are detection electrodes, formed on the substrate and extending in parallel to a first direction,
• wherein:
• the plurality of first electrodes are formed by electrically connecting a plurality of first mesh cells constituted by a fine metal wire,
• an angle θ between the fine metal wire and the first direction satisfies 0°<θ<90° or 90° <θ<180°,
• the plurality of first electrodes have at least one auxiliary fine metal wire extending in the first direction, intersecting the fine metal wire, and electrically connected to the fine metal wire,
• an angle β between the auxiliary fine metal wire and the fine metal wire satisfies 0°<β<180°,
• a total length of the auxiliary fine metal wires included in the plurality of first electrodes in the first direction is 50% to 250% of a length of the plurality of first electrodes, and a length of one auxiliary fine metal wire included in the plurality of first electrodes in the first direction is 25% to 100% of a length of the plurality of first electrodes,
• in the plurality of first electrodes, an electrode width Wa that is a minimum width in a second direction orthogonal to the first direction and a first mesh pitch P1 of the first mesh cell in the second direction satisfy Wa≤2.5P1,
• wherein an electrode width Wa of a first electrode which is arranged on the outermost side in the second direction among the plurality of the first electrodes is smaller than an electrode width Wa of the other plurality of first electrodes,
• wherein the first mesh pitch P1 is an average value of distances in the second direction between centroids of two first mesh cells adjacent to each other in the second direction, and
• on condition that two first mesh cells are not arranged adjacent to each other in the second direction in the plurality of first electrodes, a virtual centroid of a closed shape surrounded using an extension line formed by extending the fine metal wire constituting the first mesh cell in an extending direction is regarded as the centroid of the first mesh cell;
• wherein the conductive member for a touch panel further includes:
• a connecting fine metal wire that connects the auxiliary fine metal wire and the fine metal wire with each other, and
• wherein an angle between the connecting fine metal wire and the auxiliary fine metal wire is not a constant value.
